Summary
The dam on Lewis Creek, completed in 1981, is an earth dam with a hydraulic height of 28.2 feet and a structural height of 34.8 feet. It serves the primary purpose of water storage, with a capacity of 770 acre-feet and a drainage area of 0.48 square miles.
The dam has a high hazard potential but is currently in satisfactory condition, as of the most recent inspection in March 2021. The risk assessment for Lewis Creek rates it as moderate (3), indicating a level of potential risk that is manageable with appropriate risk management measures. The dam has an uncontrolled spillway and no outlet gates, with a surface area of 40 acres and a maximum discharge capacity that is not specified in the data provided.
Overall, Lewis Creek is a significant water resource in Tennessee, providing storage capacity for water management in the region. Enthusiasts interested in water resources and climate change will find Lewis Creek to be an essential part of the state's infrastructure, with careful monitoring and management in place to ensure its continued safety and functionality.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
